IMPROVEMENT IN COTTON-SWEEPS.

Specication forming part o1 Letters Patent No. 185,722, dated December26, 1876; application tiled November 8, 1876.

To all whom it may concern Be it known that I, HARRY O. BUIIoUP, ofPittsburg, in the county of Allegheny and State of Pennsylvania, haveinvented certain new and useful Improvements in Cotton- Sweeps; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit pertains to make and use it, reference being had to the accompanyingdrawings, which form part. of this specification.

My invention relates to cotton-sweeps; and is designed to afford a readymeans whereby the point to a sweep may be removed and replaced as it isworn away. It is peculiarly desirable in agricultural implements of thisclass that some way may be obtained by which the heavy and unworn partsof the sweep may be preserved as still of practical use, and that samemay not be rendered useless by the wear and eectual disqualification ofits workiilgerlge. The upper portion ot' a sweep is but little subjectedto the wearing action met by the lower and point part ot' the sweep,and, hence, is usually in a good and serviceable condition when thepoint is deteriorated and rendered of no working avail.

My invention consists in the combination oi' parts hereinafter describedand claimed.

In the drawings, Figure l represents my improvement in plan view. Fig. 2is a section View of saine, and Fig. 3 shows the parts detached.

A is the blade ot' a cotton-sweep, constructed as is usual, and havingits point B made separate therefrom. The two sections form a squarebutt-joint as they come together, and the sectional dimension of theblade continues constant throughout its body, and is not dressed away orprovided with any uncut shoulder, but retains its full proportion ofstock or material at this point. Centrally,

relative to the width of the blade, a hole is made in cross-section,which receives the bolt a, which latter forms the connecting mediumbetween the blade and the rear tongue of the point. This tongue or rearextensive piece b is, preferably, in form oi' a triangle, having itsbase-line parallel with the joint, and its apex opposite the middle ofsame, the farthest from the working -edge of the detachable point. Thisrear extension b is likewise provided with a hole corresponding to thatin the blade, so that the bolt a may titly and securely unite the two.It is cast or made in the same piece with the point, and which latterthus forms in itself an article in the trade which may be attached to asweep. All the advantages attendant upon a removable point are thusobtained, and at same time the capacity of the blade to resist thestrain brought in an angular line ot' direction upon same is notlessened by any sectional reduction, but possesses its full and constantproportion of material resistance.

It is further apparent that a point constructed as set forth may beatt-ached to a blade, which is steel, cast-iron, or wrought, and is notrestricted to a molded blade, as would be the case were the latterattached to the point by a recessed shoulder cut in the body of theblade.

Having fully described my invention, what I claim as new` and desire tosecure by Letters Patent, is

The combination, with the blade of a cotton-sweep, ot a detachable pointconstructed with a depressed rear triangular extension, which forms anintermediate vertical face, against which abuts the front edge of theblade oi' tbe sweep, the `point being secured to the blade by means ot'a bolt passing through the blade and the rear extension ot' the point,substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this10th day of October, 1876.
